Title: Flat-pack sawing stand
Inventor: RICHARDSON MERVYN WALTER
IPC: B25H1/04
Filed: 1985-02-09
Abstract: A sawing stand comprising a generally rectangular frame with successive pairs of "push-in" locating means 13, 14 spaced along substantially the whole of the length of the frame; with one locating means 13 of each pair being situated on one longitudinal side member of the frame whilst the other locating means 14 of that pair is situated opposite the said one locating means and on the other longitudinal side member of the frame; and including at least two H-frames whose uprights 15 fit, in use, into respective ones of the pairs of locating means such that, when the stand is assembled, and stood with its rectangular frame horizontal, the H-frames rise from the rectangular frame with their uprights substantially vertical and their respective cross-pieces 17 substantially horizontal, and with the uprights and crosspiece of one H-frame substantially in alignment - when the stand is viewed end-on - with the respectively corresponding uprights and cross-piece of the or each other H-frame. <IMAGE>
Patent GB-2177034-A (GB)
Title: Machining of cam profiles
Inventor: SMITH GEOFFREY IAN
IPC: B24B19/12
Filed: 1985-04-17
Abstract: In a method of grinding a cam profile, the cam (14) is rocked back and forth (arrows 11,13) in timed relation to rotation of the cam (14) about its axis (16). The grinding wheel (18) is advanced (arrow 22) towards the cam (14) to effect stock removal. Alternatively, the cam axis is fixed and the feed movement is superimposed on a back and forth movement of the grinding wheel. In either case, after spark out, the "maximum lift" position of the cam (14) is detected and the back and forth movement is terminated at the point of maximum lift while the rotation of the cam is continued. The cam thereby separates from the grinding wheel whilst the axis of the latter is fixed. This avoids any "breakaway marks" on the cam profile, since "wind-up forces" are still tending to separate the cam from the grinding wheel at the point of maximum lift. <IMAGE>

Patent GB-2177203-A (GB)
Title: Orientation-indicating instrument
Inventor: GRAVELLE DAVID EDMUND
IPC: G01C9/28
Filed: 1985-06-05
Abstract: The instrument has two half- bodies 5, 6 which are movable relative to each other about a central pivot. The two half-bodies can thus have a cruciform configuration and a more compact parallelepiped configuration. One half-body 5 has four spirit level devices 27, 33, 37 (see Fig. 1), 43. The first two devices 27, 33, which are crossed at 45 DEG  relative to each other, and the third device 37 allow the instrument to be used in the manner of a conventional spirit level in the compact configuration. The fourth device 43 is one which orientates a plane defined by lower surfaces of the half-bodies 5, 6 when the body is in its cruciform figuration. The orientation of the fourth spirit level device may be adjustable relative to the instrument body (see Fig. 9), thus facilitating tasks such as the orientation of a paving stone to provide for run-off of rain water. <IMAGE>

Title: Integrated circuits
Inventor: ROSSER P J
IPC: H01L21/762
Filed: 1989-11-23
Abstract: In a process for fabricating an integrated circuit, device areas are defined by a nitrided oxide mask. The remaining areas of the substrate are oxidised and the mask is then removed to allow the application of contacts, e.g. polysilicon emitter bodies, to the substrate. The process significantly reduces the extent of oxide incursion or 'bird's beak' at the edge of the mask. The nitriding of the oxide mask is effected by heating it in an ammonia atmosphere. <IMAGE>

Abstract: A striking mechanism for an alarm bell assembly in which an elongate hammer 32 is suspended by spaced parallel links 36, 38 forming with the hammer and the casing a four-bar linkage. The hammer is arranged to approach impact such that the resultant motion of the hammer coincides with a normal to a tangent to the bell at the point of impact. Lost motion is provided in an oscillatory drive for the hammer so that the hammer travels beyond the limit of its driven stroke to strike the bell. The mechanism achieves a better ring effect for a given input power as compared with conventional bells. <IMAGE>
